Activity overview:

This general chemistry video tutorial focuses on le chatelier’s principle and how it relates to equilibrium. It contains plenty of examples and practice problems that will help you to prepare for your next exam or test.

Here is a list of topics:
1. Le chatelier’s principle – haber process – N2 + 3H2 = 2NH3
2. How to know which direction the reaction will shift – Basic Rules
3. Increasing and decreasing the concentration of the reactants and products
4. Equilibrium – Increasing temperature for an endothermic reaction
5. Volume Decrease, Pressure Increase – reaction shifts to the side with less moles of gas
6. Dilution, the effect of adding water to aqueous system – concentration of all species decreases
7. Changes in temperature of an exothermic reaction – heat flow into and out of system and surroundings
8. Iron Thiocyanate Equilibrium System – Fe+3 is yellow, FeSCN+2 is red, and SCN- is colorless
9. Equilibrium – Color Changes – Cobalt Chloride System Co(H2O)6+2 is pink and CoCl4 2- is blue
10. Equilibrium, Ksp, Solubility, Dissolution and Precipitation
11. Equilibrium and Electrochemistry – Gibbs free energy, spontaneous reactions, and cell potential
12. The effect of temperature on the equilibrium constant K
13. The effect of adding a catalyst on the position of equilibrium
14. The effect of adding an inert noble gas on the position of equilibrium
15. Saturated, Unsaturated, and Supersaturated Solutions
16. Ksp, equilibrium, and the effect on the pH of the solution, acids and bases
17. The effect of adding a solid on equilibrium
18. The effect on the concentration of the reactants and products as the reaction shifts to the right or to the left.
